Note1: VDD - VSS, VCC -COM and VB - VS contain internal shunt Zener diodes. Please note that the voltage ratings of these can be limited by the clamping current.
Note2: For the rising and falling edges of step signal of 10 V. Vss=15 V to 200 V.
Note3: Vss ramps up from 0 V to 200 V.
The IRS20955 is a high voltage, high speed MOSFET driver with a floating PWM input designed for Class D audio amplifier applications.
Bi-directional current sensing detects over-current conditions during positive and negative load currents without any external shunt resistors. A built-in protection control block provides a secure protection sequence against overcurrent conditions and a programmable reset timer.
The internal deadtime generation block enables accurate gate switching and optimum deadtime setting for better audio performance, such as lower THD and lower audio noise floor.
